I installed a brand new alum prop before launching for the season 2 wks ago. Boat is slipped at a marina at a freshwater lake without shore power connections at my dock. Yesterday I pulled the boat for some other maintenance issue and noticed that the paint has popped off the blades of the prop in small circles and these are raised to the touch. Last season the boat sat at the dock without much use due to a family illness. When I pulled it in the fall, there was extensive damage to that prop which is now being repaired. Looks to me like some electrolysis eating up the prop, the skeg had damage too. I replaced the zincs before the first launch this season. The only electrical component that I know had problems was a faulty stereo tuner, that I disconnected and removed. The wiring remains and I cleaned that up as best as i could. There could still be some corrosion on those wires which are live still.
Any ideas about this condition, and how do I check out the electrical current on the boat to rule things out? Thanks.
